I don't think we will have a dedicated section for it unless it really takes off. There are a bunch of android based handhelds and consoles coming, time will tell which one comes out on top and if it is in any way relevant. For now ouya fans will have to make do with the general gaming discussions/android/other systems sections.

Well, considering desktop sales are down quite a bit, and most of those companies are making mobile devices to stay afloat, I think they are headed down a much slower path. I know people still buy prebuilts, but not many people on a somewhat "hacking" forum should, or would be really all that interested in them. Building a PC now days is incredibly easy, its just like legos.
